LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 603,997, dated IVIay10, 1898.

Application led March 5 1897.

To all whom it may concern:

Be it known that I, GUs'rAv SEYFFARTH, a citizen of Germany, and aresident of Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a certain new and useful Improvement inLubricating Apparatus for Hydraulic Elevators, of which the following isa full, clear, and exact specitica tion, reference being had to theaccompanying drawings, whereinf i A Figure l is an elevation,partly-sectional view, of my lubricating `apparatus,lshowing the same inposition 'within the cylinder of'a hydraulic elevator. Fig. 2 is an endview thereof, looking in the direction of the arrow indicated in Fig. 1.Figs. 3 and 4 are detail views, drawn on enlarged scale, a front and aside elevation, respectively, of the device actuating the lubricator.Figs. 6 and 7 are enlarged sections on lines 5 5 and I6 6, respectively,indicated in Fig. 4. Figs. 7 and 8 are similar detail views, a front andside elevation, respectively, of the arms carrying the oilers andwiping-mops. Fig.A 9'is a crosssection on line9 9, indicated in Fig?Fig. l0,

' a cross-section on line l0 l0, indicated in Fig.

8; and Fig. l1, a partial view, an elevation similar to that in Fig. l,showing a modied construction of the mechanism for actuating thelubricator.

Similar letters of reference indicate corresponding parts in all viewsofthe drawings.

My invention relates to lubricating contrivances for hydraulicelevators; and it consists of the hereinafter-described apparatus for acontinuous and automatic lubricating of the elevator-cylinder during theoperation of the elevator. i

The apparatus is adapted to be attached to the piston of the hydrauliccylinder, and it consists, mainly, of an oil-carrier E, a number ofmovable oil-ladles s, lifting the oil from the oil-carrier anddistributing the same on the walls of the cylinder, a number ofmopwipers set on extensible arms and spreading the oil on the walls ofthe cylinder, and of a traveler cor some other suitable mechanism fori'3imparting a rotary motionto the lubrica or.

The parts of the apparatus are upon spin serial No.` 626,117. ou man.)

dle p, set in a cast-iron hood h, which is slid over screw-nut P8,securing piston P to the piston-rod R, and is secured thereto bysetscrews h. Spindle p is rigidly secured by screw-nut p in the apex ofhood h` and is steadied by its pointed end entering into a conicalrecess f, provided in the end of the piston-rod. On this spindle p isset the hub W, in whose hollowfstumps w, cu2, w3, and W4 are set theextensible arms A, carrying mop-wipers u, and the 'extensible arm A',carrying the traveler e. Hub W rotates on the spindle p and is held inposition thereon by screw-nut p2, an antifriction disk or washer pwbeing set betweenl the screw-nut and the base ofthehub.

Beyond the screw-nut p2 the end of spindle p is reducedin diameter toform a shoulder on which the oiler E is suspended. The oiler is securedinitsposition on the spindle p by screw-nut p3 and is always pendingvertically downward.

Arms A and A" are similarly constructed. They consist of stationaryparts a, made of /-sh'aped ehannel-iron andpermanently secured to thehub W, and of the movable or sliding parts a', snugly fitted into thestationary parts a and secured thereto in adjusted j position by theclamp c and set-screw c.

These arms A and A are made lengthwise extensible to permit adjustmentof the operating parts of the apparatus for cylinders of differentdiameters, and also to allow readjustment of them in compensationfor'wear.

On the ends of the arm A are secured by clamps ca the mop-wipers u. Onelever of the clamps is screwed to the part a ofthe eX- tensiblearms, andthe other is provided with a screw-threaded hole through which asetscrew u' passes. By turning this screw the jaws of the clamp areforced together and the body of the wiper, which may beof felt or ofsome other suitable substance, is irmly gripped and held between thejaws.` i V The sliding part a of the arm A,which carries the traveler,is provided `with .screwthreaded brackets t. Holder m, provided with anaxial boring wherein the socket a is fitted, is screwed in bracketst andlocked in adjusted position by nut-collar fm. Spiral spring IOO z, setin the same boring, presses the socket 'n outward, and spline Ilprevents it from turning in the boring. The socket n is also providedwith an axial boring into which is tted the stem of the fork n',carrying roller e on pin e2. The stem of the fork n' is secured insocket n by set-screw e. This arrangement is provided to permit anangular adjustment of the roller e in relation to cylinder C.

Roller e may be set at a more or less acute angleto the axis of thecylinder C, and consequently when the piston P andthe lubrieatingapparatus carried on it are moved through the cylinder this roller ewill cause the arms of the lubricating apparatus to rotate on spindle p.

The function of the spring ,a is to exert a steady pressure upon theroller e to increase friction between it and the inner surface of thecylinder on which it travels.

Ladles s, lifting the oil from the holder E, are secured to flexiblemetallic strips k, and these in turn are riveted to brackets b, securedto the arms A in such position that when the arms rotate the ladles swill travel through the oil-holder E, lifting the oil therefrom. Thereis one ladle or spoon s riveted to each side of the strip 7c. This isdone for the purpose to enable the lubricator to oil the 4cylinder whilethe piston moves both ways.

The bottom of the holder E is curved in conformity with the circledescribed by the ends of the ladles s; but on each end thereof the rimof its bottom is bent inwardly to form an abutment s. The elastic strip7e projects beyond the extremity of the ladles s and abuts against theseinwardly-bent rims s', whereby a throwing motion is imparted to ladless, causing the oil filled therein to be thrown quite forcibly againstthe walls of the cylinder.

The operation of the apparatus is as follows: During the motion of thepiston P each of the ladles s will pass through the oil-holder E, beimmersed successively in the oil, and lift a quantity thereof,distributing the same on the walls of the cylinder in the manner asdescribed above. Mop-wipers u, being also secured to the rotatingarms,will at the same time travel near the inner surface 'of thecylinder, there being only a slight clearance between the surfacesthereof and the surface of the cylinder, and will spread the oil. Itmust be observed that each of these wipers describes a separate spiralline on the surface of the cylinder, and consequently each succeedingwiper will continue the spreading of the oil escaping from the precedingone, and in this manner a thorough distribution of the oil is obtained.

In the modiiied construction shown in Fig. 1l there is a friction-wheelX, revolving on a pin set in bracket m2, and provided on one facethereof with a bevel-gear engaging the bevel cog-wheel j, set on aspindle fin bracket On the other end of spindle jz is rigidly keyed toit a beveled cog-wheel j', driving-gear 0, secured to the parts a of theextensible arms A and Al of the lubricating apparatus. This somewhatmore complicated mechanism for imparting a rotary motion to thelubricating apparatus would be required only in large cylinders, whereinthe driving device (shown in Fig. 2 and described above) could not beused for rotating the lubricating apparatus. This latter device (shownin Fig. 2) is, however, preferable for ordinary purposes. If one rollere should not be sufficient in apparatuses of larger size, then two ormore of them may be added, constructed in the same manner, and the armsfor carrying them could be placed between the arms A in the same manneras the one shown in Fig. 2. The means of connecting the apparatus to thepiston-rod can be varied as the size of the apparatus and othercircumstances may require.
